SYPT H-EUPEX high flexible couplings are for shaft connection of machines,they compensate for shaft misalignment,generating only low restorative forces.

The torque is conducted through elastomer flexibles, so the coupling has typically flexible rubber properties.

The flexible inserts of the H-EUPEX coupling are subjected to compression. If the flexible inserts are irreparably damaged, the hub parts come into contact with metal. This "emergency operation capability" is required, etc., in the case of fire pump drives.

The motor torque is transmitted to the hub at the drive end via the shaft-hub connection, which is mostly designed as a keyway connection. The torque is transmitted to the hub on the output side with the aid of elastomer flexible inserts. The hub on the output side further transmits the torque to the driven machine or a gear unit placed in between. Because of the primarily compressionloaded elastomer flexible inserts, the coupling has a progressive torsional stiffness.
